2 Claims.

This invention relates to new and useful improvements in tools or implements for replacing the usual cut-out door on high voltage fuse cutouts.

The principal object of the present invention is to provide an implement of the character described which can be used to considerable advantage by linemen and other workmen who maybe engaged in refusing high voltage cut-outs.

Other objects and advantages of the invention will become apparent to the reader of the follow ing description.

In the drawings- Figure 1 represents a fragmentary front elevational view of the upper portion of the implement.

Figure 2 is a fragmentary side elevational view showing the implement door.

Figure 3 is a fragmentary front elevational view of the upper portion of the implement with the jaws in open position. i

Figure 4 is a top plan view of the implement with the jaws in the position shown in Figure 1.

Figure 5 is a horizontal sectional view taken substantially on the line 5-5 of Figure 2.

Referringfto the drawings wherein like nuengaged with a cut-out ,merals designate like parts, it can be seen that numeral 5 denotes a cut-out door having the usual eyeG. i i

Numeral 1 generally refers to the improved implement which consists of an elongated pole 8 preferably of wood or some suitable insulation. The upper portion of this pole 8 is reduced and over this is slipped a ferrule 9 upwardly from which projects a pair of transversely arcuate wing-members I0 spaced horizontally as shown in Figure 1 to receive the eye 6 of the cut-out door 5.

A U-shaped contractor II has its ends Welded or otherwise secured to the wing members ID. A pair of arcuate-shaped jaws, l2, l2 having interlapping end portions l3 are provided with straight shanks l 4 pivotally connected together and within the bifurcated upper end of a connector I 5, as at [6.

Slidable through suitable guides ll on the pole 8 is an elongated rod l8 of wood or some other insulation, the upper end of this rod l8 being se- I cured as at i9 within the connector I5.

A coiled compression spring 20 -is interposed between the shanks l4, I4, as shown in Figure 1 so as to separate thejaws when the rod I8 is pushed upwardly.

It can beseen, that cut-out door can be reached from a distance, depending upon the length of the pole 8.

'Ihe cut-out door 5 can be easily manipulated by straddling the eye 6 of the door with the wing members I0 andwith the jaws l2 in the open position shown in Figure 3. By pulling downwardly on the rod Hi, the jaws are caused to contract as they move through the contractor I I, thus closing the jaws to form a link, linked with the eye 6. The tool thus connected to the door 5 can be manipulated to properly adjust the door.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

as new is: i

1. An implement of the character described comprising a head structure, an elongated pole, a gripping device on the head and means extending along the pole for operating the gripping device; said gripping device consisting of a pair of pivotal jaws, spring means for spreading the jaws and contracting means for contracting the jaws when the means extending along the pole is operated. j

2. An implement of the character described comprising a head structure, an elongated pole, a

gripping device on the head, and means extending along the pole for operating the gripping device,

said gripping device consisting of a pair of pivotal 'jaws, spring means for spreading the jaws, and contracting means for contracting the jaws when the means extending along the pole is operated. said contracting means comprising a member on the head through which said jaws are slidably extended and acting to cam said jaws together.
